An articular support system for dental model sets includes a fixture having an upper portion carried by a lower base portion. The base portion has a base plate which connects with an inner support post. This post is formed with a vertically extending inner passageway. The upper portion includes an inner and outer plate connected by a releasable hinge. To use the system a base of a dental model of a person's upper teeth and lower teeth are each molded with front and rear indentations. Each model then fits into a bracket having spaced apart end walls. On an inner side of each end wall is a locking tab that fits into the respective model indentations. The lower teeth model bracket next is affixed to the fixture base plate with mastic. The upper model teeth then are placed in contact with the lower model teeth to reproduce the bit that occurs inthe person's mouth. Next, the upper portion inner plate is loosely positioned in the base portion post passageway. With the outer plate positioned on top of the upper teeth model bracket, the plate and bracket are joined together with mastic. Lastly, the upper portion inner plate is secured with mastic in the post passageway. During preparation of crowns, dentures and like appliances, the models may be readily removed from the fixture and then reattached with the bite positioning accurately and reliably reproduced.

The module for an apparatus (system) to produce upper and lower jaw full prostheses has an instrument holder (66) consisting of a baseplate (3), supporting two upright pillars (4) and a tilting arm (6) that can be pivoted on a horizontal axis (5) around the pillars (4), on which auxiliary instruments developed for individual work processes can be adapted.In terms of auxiliary instruments, the module has an infinitely adjustable levelling table (9) set on the baseplate (3), a lower jaw alignment key (10), an impression or mounting plate (7, 8), an upper jaw model alignment key, a domed setting aid for correct setting of teeth on the lower jaw full prosthesis and a domed setting aid with dummy tooth for correct setting of the 1st right and left tooth on lower jaw full prostheses, which can be attached to the instrument holder (66) in a secure position and interchanged.

A dental articulator includes a pair of attachment members, each adapted to engage a dental casting and a hinge unit including two pivotably interconnected retaining members, each adapted to engage one of the attachment members by means of a joint which may be selectively and reversibly immobilized. The two retaining members are interconnected by a hinge which provides a pair of spaced apart pivot axes for pivoting each of said members and which further provides for the ready and reversible separation thereof.
摘要:
A rigid, non-yielding precision dental articulator instrument for preserving and making available the occlusion plane required to build accurate incuspation of teeth. The device provides initial mounting of maxillary models using a facebow. A 20 degree sliding mounting plate is also provided for aiding in the setting of the Occlusal Plane.

A device for use with an articulator in the construction of artificial dentures, comprising a base adapted to be placed on the articulator, a tabletop on the base, the height of which is adjustable; and a removable template adapted to be pivotably mounted to a cradle provided in said tabletop. A knife edge unit with spaced apart knife edges, and a spear box and pointer adapted to be raised or lowered by means of a ramp and associated adjustment screw is removably attached to said base in a manner such that said spear box is guided for movement along said ramp by threaded means in simultaneously both upward and forward directions, and the pointer being adapted to retain in place thereon an upper rim impression and tray prior to its being mounted to an upper mounting ring of the articulator.

A dental articulator has a tooth supporting tray secured to a platform by a key and keyway wherein the sidewalls of the keyway are resiliently supported to permit yielding of the sidewalls to overcome any clogging by particulate matter which may be present in a place of use of the articulator. A set of legs upstanding from the tray maintains orientation of the tray relative to the platform.

Duplicatable maxillary denture materials, e.g., partial or complete dentures, wax-ups and bite blocks, are prepared employing the relator assembly and process of the invention. The process involves forming the maxillary denture materials from a rough maxillary cast of the patient's mouth that has a base and an expression of the maxillary alveolar ridge including the anterior palatine papilla and hamular notches. In the process, the cast is suspended over a horizontally extending, flat occlusal base member at a predetermined height corresponding to the proposed incisal length of the denture materials with members of substantially equal height, located on the occlusal table, that contact the cast at the palatine papilla and hamular notches. The base of the suspended rough cast is luted to a maxillary base member that is located over and substantially parallel to the occlusal base member to form a cast whose base is parallel to the hamular-incise plane. Thereafter denture elements, individual artificial teeth or bite-block elements are arranged on the occlusal base member in a predetermined location relative to the cast luted to the maxillary base member and corresponding to the proposed labial drape of the patient. The aforesaid denture elements, individual teeth or bite-block elements are then luted to the alveolar ridge of the cast mounted on the maxillary base member.
摘要:
A dental model supporting articulator has an upper articulation tongue and a lower articulation tongue and pivotal means connecting the tongues to each other; first and second dental model mounting plastic slide members are removably mounted on the upper and lower articulation tongue members. Each slide member has retaining flanges and positioning means engageable with an articulation tongue member for insuring that the slide member is always accurately positioned in a single unchanging position on the tongue member; each slide also has anchor means engageable with a connecting mass of self-setting hardenable material in which the gum portion of a dental model is embedded so that upon hardening of the connecting mass the model supporting slide, the connecting mass and the model constitute a unitary structure which can be removed from the articulation tongue but can be returned to its original position on the articulation tongue.
摘要:
A dental occluder comprising top and bottom arms having base elements and matrix supports secured to each of the arms, the matrix supports each being angularly adjustable relative to the base elements and the respective arms, and the matrix supports being readily detachable from the base elements without alteration of the angular relationships of the base elements, the arms, and the matrix supports.

Dentures or denture elements that are anatomically related to Camper's Plane are prepared employing the relator assembly of the present invention. The relator assembly is composed of (i) a vertically disposed support that is maintained in position with a stand member; (ii) a horizontally disposed occlusal base member; (iii) a maxillary base member that is pivotably connected to the upper portion of the support, the lower surface of the maxillary base member positioned in substantial vertical alignment with and in a plane parallel to the upper surface of the occlusal base member; (iv) cast positioning element located on the lower surface of the maxillary base member; (v) a labial drape locator that is adapted to be positioned on and removed from the upper surface of the occlusal base member; and (vi) an arch locator that is adapted to be positioned on and removed from the arch locator holder element of the labial drape locator.
